Initial analysis

The two-story multi-family residential building at 509-511 Capp Street in San Francisco's Inner Mission district, owned by the Gary A Combatalade Revocable Trust, was constructed in 1890 and contains three units. The building's permit history shows several significant maintenance and structural improvements, including a major project in 2001 that involved removing garage posts and capping perimeter footings at a cost of $25,000, though this work was noted as not being part of a seismic upgrade. Earlier permits from 1996 (reroofing) and 1987 (entry stairs and exterior fascia repair) indicate regular maintenance was performed, but these permits have since expired.

Recent activity at the property has included several notable incidents in 2023-2024, with the most concerning being a sewage backup incident in October 2023 that required intervention from PUC Sewer Operations. The building has experienced multiple noise complaints, with two reports in December 2024 (one of which was invalid as it fell outside 311's jurisdiction), and there have been several issues with street cleanliness and abandoned items nearby, including reports of garbage and debris in July 2024 and January 2023. The property has also faced external challenges, including an encampment situation reported in October 2022, hazardous materials (glass) clean-up in July 2018, and two instances of graffiti, though these were resolved promptly. The building's documented history shows regular maintenance and response to issues as they arise, with the most recent significant structural work occurring over two decades ago.

Risk rating

How 509-511 Capp St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
